Effects of Pantothenic Acid on Growth Performance, Oxidative Stress, and Lipid Content in High-Fat-Fed Megalobrama amblycephala

This study was to elucidate the effects of dietary pantothenic acid (PA) on growth, lipid metabolism, and antioxidant status in juvenile blunt snout bream Megalobrama amblycephala. Fish were fed with four experimental diets containing two lipid levels (5% and 11%) and two PA supplementation levels (24 mg kg-1 and 240 mg kg-1) for eight weeks. The results showed that diets containing 11% lipid significantly increased condition factor, mesenteric fat index, triacylglycerol (TG), and cholesterol (TCH) in the liver as well as total lipid content and TCH in the muscle ( P < 0.05 ), but significantly decreased specific growth rate and whole-body protein ( P < 0.05 ). As the dietary lipid level increased, hepatic antioxidant enzyme activities were significantly increased ( P < 0.05 ) as well as malondialdehyde content ( P < 0.05 ). Besides, cytosolic cytochrome c concentration was also significantly ( P < 0.05 ) increased, while mitochondrial protein, cytochrome c, and Na+-K+-ATPase activities were significantly decreased ( P < 0.05 ). There were no significant changes on growth performance and body composition of PA supplementation. Then, significantly negative ( P < 0.05 ) interactions were observed between dietary lipid and PA supplementation on EPA, DHA, and EPA + DHA content of the muscle. Saturated fatty acid (SFA) and polyunsaturated fatty acid (PUFA) contents in the liver were significantly increased ( P < 0.05 ) with dietary lipid level increased, while liver monounsaturated fatty acid (MUFA) was significantly decreased ( P < 0.05 ). Muscle SFA, DHA, and EPA + DHA contents were significantly decreased ( P < 0.05 ) when dietary fat level increased. Meanwhile, EPA, DHA, and EPA + DHA content was significantly decreased ( P < 0.05 ) with dietary high PA supplementation. On the whole, a high PA supplementation level of 240 mg kg-1 could alleviate lipid content accumulated and oxidative damage induced by a high-fat diet.

Effect of supplemental pantothenic acid on lipid metabolism and antioxidant function of Apis mellifera worker bees

This study was conducted to investigate the effects of pantothenic acid (PA) on the lipid metabolism, and antioxidant function of Apis mellifera workers. The results showed that ether extract (EE) content of bees’ body was significantly decreased when workers were supplemented with 147 mg/kg PA (P < 0.05). Further, supplemental PA reduced triglycerides (TG) and total cholesterol (TCHO) content in the hemolymph (P < 0.05), while 39.2 mg/kg PA supplementation improved hemolymph high-density lipoprotein cholesterol (HDL-c) concentration, while 261.6 mg/kg PA reduced low-density lipoprotein cholesterol (LDL-c) concentration (P < 0.05). C12:0, C14:1, and C18:0 content values were notably increased in PA-supplemented groups, while those of C14:0, C18:2n-6, C20:4n-6, polyunsaturated fatty acids (PUFA), and PUFA/saturated fatty acids were decreased (P < 0.05), while levels correlated with those of dietary PA. Malondialdehyde (MDA) content showed a downward trend in response to PA supplementation; however, total superoxide dismutase (T-SOD) was increased (P < 0.05). Furthermore, fatty acid synthase (FAS) mRNA levels were significantly downregulated in bees supplemented 9.8, 19.6, and 39.2 mg/kg (P < 0.05) and lipase activity significantly improved following supplementation with 39.2, 78.4, and 147 mg/kg PA (P < 0.05). Thus, dietary PA significantly influenced worker bee lipid metabolism, and improved antioxidant function.

Effects of pantothenic acid on growth performance and antioxidant status of growing male white Pekin ducks

An experiment was conducted to investigate the effects of dietary pantothenic acid levels on growth performance, carcass traits, pantothenic acid status, and antioxidant status of male white Pekin ducks from 15 to 42 D of age and to evaluate the requirement of this vitamin for growing ducks. Different levels pantothenic acid (0, 2, 4, 6, 8, and 10 mg/kg) were supplemented to a corn-soy isolate protein basal diet to produce 6 dietary treatments with different analyzed total pantothenic acid levels (4.52, 6.44, 8.37, 9.88, 12.32, and 14.61 mg/kg). A total of 240 15-day-old male white Pekin ducks were allotted to 6 dietary treatments with 8 replicate pens of 5 birds per pen. At 42 D of age, growth performance, carcass traits, tissue pantothenic acid concentrations, and antioxidant status of white Pekin ducks were examined. Significant effects of dietary pantothenic acid on BW, average daily weight gain (ADG), plasma, and liver pantothenic acid concentrations were observed (P < 0.05) but not carcass traits. The growing ducks fed the basal diet without pantothenic acid supplementation had the lowest BW, ADG, plasma, and liver pantothenic acid content among all ducks (P < 0.05). In addition, the ducks fed the basal diet without pantothenic acid supplementation showed the lowest antioxidant capacity indicated by greatest plasma malondialdehyde content and lowest liver total antioxidant capacity (P < 0.05). And, these criteria responded linearly as dietary pantothenic acid levels increased (P < 0.05). These results indicated that dietary pantothenic acid supplementation improved growth performance and antioxidant status of the growing ducks. In accordance with the broken-line model, the pantothenic acid requirements (based on dietary total pantothenic acid) of male white Pekin ducks from 15 to 42 D of age for BW, ADG, and plasma and liver pantothenic acid contents were 10.18, 10.27, 12.06, and 10.79 mg/kg, respectively.

Effects of pantothenic acid and folic acid supplementation on total tract digestibility coefficient, ruminal fermentation, microbial enzyme activity, microflora and urinary purine derivatives in dairy bulls

AbstractThe effects of pantothenic acid (PA) and folic acid (FA) addition on digestibility coefficient, ruminal fermentation and urinary purine derivative (PD) excretion in dairy bulls were evaluated. Eight rumen-cannulated Holstein dairy bulls were allocated to a replicated 4 × 4 Latin square design according to a 2 × 2 factorial arrangement. Diets were supplemented with two levels of FA (0 or 8.0 mg/kg dietary dry matter [DM]) and two of PA (0 or 60 mg/kg DM). The PA × FA interaction was not significant for all variables. Both supplements increased DM intake and average daily gain, but decreased a feed conversion ratio. Digestibility of DM, organic matter, crude protein and neutral detergent fibre increased, but ether extract digestibility was unchanged for both supplements. Digestibility of acid detergent fibre only increased with FA supplementation. For both supplements, ruminal pH and ammonia nitrogen (N) decreased, but total volatile fatty acid (VFA) concentration increased. Acetate proportion only increased with FA supplementation. Propionate proportion decreased for both supplements. Consequently, the acetate to propionate ratio increased. For both supplements, activity of xylanase and pectinase, population of Ruminococcus albus, R. flavefaciens, Fibrobacter succinogenes and Ruminobacter amylophilus and total PD excretion increased. Additionally, activity of carboxymethylcellulase, cellobiase, α-amylase and protease, and population of total bacteria, fungi, protozoa, methanogens, Butyrivibrio fibrisolvens and Prevotella ruminicola increased with FA addition. The results suggested that PA and FA supplementation stimulated ruminal microbial growth and enzyme activity, resulting in an increased digestibility coefficient and ruminal total VFA concentration in dairy bulls.

EFFECTS OF PANTOTHENIC ACID AND RIBOFLAVIN DEFICIENCY ON WATER METABOLISM

Effects of Pantothenic Acid and Riboflavin Deficiency on Water Metabolism Nutrition Reviews, Volume 5, Issue 7, July 1947, Pages 217–218, https://doi.org/10.1111/j.1753-4887.1947.tb04212.x Published: 01 July 1947

Effects of Pantothenic Acid on Testicular Function in Male Rats

Pantothenic acid (PaA) is a water-soluble vitamin required to sustain various physiological functions in animals. The physiological roles of PaA on testicular function, in particular, testicular endocrinology and sperm mortility, were investigated in rats. Male rats at 3 weeks of age were fed a PaA-free diet or a 0.0016% PaA diet (control) for 7 weeks. Total body weight, as well as the weights of the liver, kidney, pituitary, testis, epididymis, seminal vesicle and prostate; sperm motility; and the plasma concentrations of luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone and corticosterone were measured in rats at 10 weeks of age. Body weight gain decreased from 5 weeks of age in rats fed the PaA-free diet compared with the control. The relative weights of the testes were significantly higher in the PaA-deficient group compared with the control group. Several parameters of sperm motility were significantly reduced in the PaA-deficient group compared with the control group. In addition, the plasma concentrations of testosterone and corticosterone were significantly lower in the PaA-deficient group compared with the control group, whereas the plasma concentrations of FSH and LH showed no change. These results clearly demonstrate that PaA is an essential factor in testicular endocrinology and sperm motility in male rats.

Effects of pantothenic acid on growth performance and carcass characteristics of growing-finishing pigs fed diets with or without ractopamine hydrochloride1

Two experiments evaluated effects of added pantothenic acid on performance of growing-finishing pigs. In Exp. 1, 156 pigs (PIC, initial BW = 25.7 kg) were used in a 3 x 2 x 2 factorial to evaluate the effects of added pantothenic acid (PA; 0, 22.5, or 45 ppm), ractopamine.HCl (RAC; 0 or 10 mg/kg), and sex on growth performance and carcass traits. Pigs were fed increasing PA from 25.7 to 123.6 kg (d 0 to 98) and RAC for the last 28 d before slaughter. Increasing the amount of added PA had no effect (P > 0.40) on ADG, ADFI, or G:F from d 0 to 70. A PA x sex interaction (P < 0.03) was observed for ADG and G:F from d 71 to 98. Increasing the amount of added PA increased ADG and G:F in gilts, but not in barrows. Increasing the amount of added PA had no effect (P > 0.38) on carcass traits. Added RAC increased (P < 0.01) ADG and G:F for d 71 to 98 and d 0 to 98 and increased (P < 0.01) LM area and percentage lean. In Exp. 2, 1,080 pigs (PIC, initial BW = 40.4 kg, final BW = 123.6 kg) were used to determine the effects of increasing PA on growth performance and carcass characteristics of growing-finishing pigs reared in a commercial finishing facility. Pigs were fed 0, 22.5, 45.0, or 90 mg/kg of added PA. Increasing the amount of added PA had no effect (P > 0.45) on ADG, ADFI, or G:F, and no differences were observed (P > 0.07) for carcass traits. In summary, adding dietary PA to diets during the growing-finishing phase did not provide any advantages in growth performance or carcass composition of growing-finishing pigs. Furthermore, it appears that the pantothenic acid in corn and soybean meal may be sufficient to meet the requirements of 25- to 120-kg pigs.

Effect of pantothenic acid on hippurate formation in sodium benzoate-treated HepG2 cells.

Inborn errors of urea synthesis result in hyperammonemia. Sodium benzoate (SB) therapy has been beneficial in the treatment of hyperammonemia. It conjugates with glycine to form hippurate, which is then excreted. SB has also been used to treat children with nonketotic hyperglycinemia (NKH), where glycine is removed, on conjugation, as hippurate. In mammalian liver mitochondria, SB is activated by an ATP-dependent reaction to its CoA ester, before conjugation with glycine. Pantothenic acid (PA) is the precursor of CoA. In this investigation, increasing the amounts of PA increased CoA levels in HepG2 cells. It also significantly increased formation of hippurate in SB-treated cells. These findings suggest a beneficial effect of PA on the SB therapy in children with NKH as well as hyperammonemia.

Effects of pantothenic acid on postoperative adhesion formation in a rat uterine horn model.

This randomized blind study evaluated the effect of pantothenic acid on postoperative adhesion formation in euestrogenic and hypoestrogenic environment. We used the rat uterine horn model in a university-based laboratory setting. Thirty-six Sprague-Dawley rats were randomized into two estrogenic environments: euestrogenic and hypoestrogenic. The hypoestrogenic condition was achieved in 21 rats by either the administration of gonadotropin releasing hormone agonist or ovariectomy. The remaining 15 rats were untreated and remained in the regular estrogenic state. The left uterine horn was subjected to a lesion by serosal denudation at laparotomy. Following the uterine horn surgery, the rats within each environment were randomized into three treatment groups: saline (control), intraperitoneal pantothenic acid and intramuscular pantothenic acid. The degree of adhesions ten days following surgery was scored by an evaluated blinded to the rat's estrogenic condition and treatment. In the hypoestrogenic environment, there were no differences in the mean adhesions scores by treatment. In euestrogenic rats, the intraperitoneal pantothenic acid group had a higher mean adhesion score than intramuscular pantothenic acid, but neither treatment mean differed from that of the saline group. There was no difference in the mean adhesion scores of the saline groups by estrogenic environment. We concluded that pantothenic acid was not found to decrease adhesions formation when administered intraperitoneally or intramuscularly at these dosages. Contrary to previous reports, the hypoestrogenic condition alone was not found to be associated with decreased adhesion formation in our study.

Effect of Pantothenic Acid and Ascorbic Acid Supplementation on Human Skin Wound Healing Process

This study aimed at testing human skin wound healing improvement by a 21-day supplementation of 1.0 g ascorbic acid (AA) and 0.2 g pantothenic acid (PA). 49 patients undergoing surgery for tattoos, by the successive resections procedure, entered a double-blind, prospective and randomized study. Tests performed on both skin and scars determined: hydroxyproline concentrations, number of fibroblasts, trace element contents and mechanical properties. In the 18 supplemented patients, it was shown that in skin (day 8) Fe increased (p < 0.05) and Mn decreased (p < 0.05); in scars (day 21), Cu (p = 0.07) and Mn (p < 0.01) decreased, and Mg (p < 0.05) increased; the mechanical properties of scars in group A were significantly correlated to their contents in Fe, Cu and Zn, whereas no correlation was shown in group B. In blood, AA increased after surgery with supplementation, whereas it decreased in controls. Although no major improvement of the would healing process could be documented in this study, our results suggest that the benefit of AA and PA supplementation could be due to the variations of the trace elements, as they are correlated to mechanical properties of the scars.

Effect of pantothenic acid on disposition kinetics and tissue residues of sulphadimidine in chickens

Sulphadimidine was administered to chickens via the intracrop route to determine plasma concentrations of the unchanged sulphonamide and its acetylated derivatives, kinetic disposition, tissue residues and acetylation. The sulphadimidine was given alone (group 1) at a dose of 200 mg kg −1 bodyweight. Pantothenic acid was given via the intracrop route at a dose of 100 mg kg −1 bodyweight one hour before (group 2) and six hours after (group 3) sulphadimidine administration (200 mg kg 1 ̄ body-weight intracrop). The highest plasma concentrations of sulphadimidine in groups 1, 2 and 3 were reached in 1·73, 1·62 and 1·71 hours, respectively, following intracrop administration. In birds of groups 1, 2 and 3 no sulphadimidine was detected at 72, 24 and 48 hours, respectively, following its administration. Estimation of sulphadimidine in most of thebody tissues revealed that all tissues examined had lower concentrations than plasma. In chickens given pantothenic acid (groups 2 and 3) before and after sulphadimidine administration, an increase in the concentration of N 4 acetylated derivatives of sulphadimidine was observed compared with birds given sulphadimidine alone (group 1).

The effects of pantothenic acid, cysteine and dithiothreitol in intact, reperfused pig hearts

The objective of this study was to augment myocardial tissue levels of amphiphiles using a treatment protocol of pantothenic acid, cysteine and dithiothreitol (DTT) in 24 hr fasted pigs and to test their influence on mechanical recovery in reperfusion. Eighteen pig hearts were extracorporeally perfused aerobically, subjected to regionally reversible ischemia in the left anterior descending perfusion system and reperfused. Nine hearts served as a placebo group; nine hearts were treated. All hearts received trace-labeled palmitate to measure fatty acid oxidation and were perfused with an infusion of 20% Intralipid to augment perfusate levels of fatty acids. Fasting alone in the presence of carbon substrates in the coronary perfusate was not sufficient to de-inhibit pantothenic acid kinase such that CoA synthesis was not enhanced. Tissue contents of triacylglycerols and phospholipids in reperfused myocardium were no different than in aerobic heart muscle but free CoA and free and total carnitine were reduced, suggesting a leakage of cytosolic contents across injured sarcolemma. Treatment significantly impaired mechanical recovery during reflow, presumable due to the noxious properties of DTT whose reported effects in heart muscle are wide ranging, difficult to predict in intact hearts and may be harmful.

Effects of Pantothenate Deficiency on Steroid Hormone Secretion in Rats

The effect of pantothenic acid (PA) deficiency on the adrenocortical function was investigated in young male rats fed a PA-deficient (PAD) diet over a period of about three months. Pair-weight (PW) and ad libitum (AL) fed rats served as controls. Basal 08.00h (lights on) plasma levels of corticosterone were regularly found to be reduced in PAD and AL rats compared with those in PW animals. Investigation of the circadian rhythm of plasma corticosterone revealed that the elevated 08.00h hormone concentrations of PW rats are due to a biphasic 24-h pattern of plasma corticosterone with a distinct glucocorticoid peak at lights on and another one at lights off (20.00h), whereas PAD and AL rats only show one clear increase in plasma corticosterone levels at the beginning of the dark period. However, the evening glucocorticoid peak of the PAD rats was markedly higher than that of the PW and AL groups. Thus an adrenocortical overactivity is ascertained in PA deficiency which is presumably responsible for the adrenal hypertrophy generally observed in earlier studies on PA depletion in rats. Multiple examinations of the secretory capacity for corticosterone, each carried out half an hour after i.m. administration of 2.5 IU ACTH1-24, revealed comparable plasma responses to supraphysiological ACTH stimulation in PAD, PW, and AL rats. Therefore we concluded that corticosterone secretion is not impaired in PA deficiency, at least not that elicited for short periods by adrenocortical overstimulation. Additional measurements of the adrenal cholesterol content and the circadian plasma levels of dehydroepiandrosterone-sulphate were carried out in all three diet groups. The respective results are discussed with regard to the stress situation produced by the experimental PA deficiency.

The Effect of Pantothenic Acid in the Diet of Growing Chicks on Energy Utilization and Body Composition

Two experiments were conducted to investigate the effects of varying levels of pantothenic acid on the efficiency of energy utilization and changes in body composition of the growing chick. The results indicate that a pantothenic acid deficiency does not interfere with the chick’s ability to obtain metabolizable energy from the diet. The data do show that the efficiency of energy utilization and body composition were markedly affected when chicks were fed diets deficient in pantothenic acid. In both experiments, protein, fat and energy stores were significantly reduced when pantothenic acid-deficient diets were fed. Increased estimates of heat increment per gram of diet were observed when levels of pantothenic acid below the N.R.C. (1971) recommended level of 10 mg. per kg. of diet were fed.

Pantethineの生物学的研究(X) Pantethineの胃腸管運動亢進作用に対する麻酔薬の影響

The intestinal motility-promoting effect of pantethine was examined in rabbits, dogs and mice under various anesthetic conditions. In rabbits (Trendelenburg's method), the effect was easily detectable when the animals were anesthetized with pentobarbital or urethane or immobilized with d-tubocurarine chloride, but not in the case of α-chloralose anesthesia. In dogs (balloon method), on the contrary, the effect was easier to be detected under α-chloralose anesthesia rather than urethane anesthesia. On the other hand, the promotive effect of pantethine on the passage of charcoal meal through mouse intestine could not be found under anesthesia with urethane or α-chloralose, though it was detectable under pentobarbital anesthesia. The effect of pantethine concerned was considered to be chlinergic as it was augmented by neostigmine and antagonized by atropine. The influence of anesthetics on the effects of pantothenic acid, neostigmine, carpronium chloride and bethanechol chloride have also been described.
